Not to be rude or harsh, and no, that isn't an excuse for any unmeant harshness to follow. But if you don't mind my asking, why do you want to write a novel so badly if reading them doesn't interest you?
I'm always reading, and for me that translates into a love of writing.I go through cycles where I will read only original work, where I read only fanfiction, and where I read both. No matter what, though, I am always reading something. Be it a a slew of drabble length fanfics, short story fanfics, original shorts, long fanfics and original work etc. I am reading. Sure I avoid things like omegaverse like the plague when reading fanfic, but there's more out there than omegaverse stuff. If I didn't like ANY fanfic on the other hand, I wouldn't dare write it. It would be illogical to write something I don't personally enjoy or to think I'm better than all those fanfic writing hacks out there.
Likewise I read original stuff because I enjoy it and avoid the things I obviously don't enjoy. You said that your prefered genre is YA Fantasy, are we talking standard type of psuedo-Medieval Fantasy or something more like Urban/Contemporary Fantasy? From the books you've talked about reading recently, it seems you may have to widen your scope of what fantasy is. Maybe read some adult fantasy of various subgenres, or at least explore other forms of YA Fantasy. Heck, maybe even branch out into SF and Horror. SFFH is part of a genre family called Speculative Fiction, and if that doesn't work try more contemporary stories. Being only a few months shy of 24, I have to say that this is likely just a phase. In the past 6 years, I've changed a lot. My basic taste is the same, but now I have subject matter I no longer read in either fanfiction or original works. My taste has evolved away from those things, and I'm just now starting to incorperate properly done stories with the offensive subject matter included back into my reading diet. I've gone from devouring everything in site, to being more selective.
You may just be entering your extra picky phase, so don't give up on reading completely. But to answer your core question, it is a one in a million shot that you're one of the few people in the world able to write extremely well depite not liking reading. It can happen, anything is possible in theory. Only, this is one of those extremely super unlikely possibilities. I wouldn't bet on it.
